Nassda Granted Patent for Hybrid Circuit Timing Analysis
SANTA CLARA, Calif., Dec. 15 /PRNewswire-FirstCall/ -- Nassda Corp.
(NASDAQ:NSDA) today announced it has been issued a patent by the United States
Patent and Trademark Office for its method of describing a hybrid system of
static analysis and dynamic simulation for IC design verification. The patent,
#6,820,243, covers technology, which is used for circuit-level timing and
crosstalk analysis of leading-edge custom digital designs at 130nm processes
and below.
"This patent forms the basis for a new innovative approach to circuit-level
timing analysis," said Graham Bell, Senior Director of Marketing. "It describes
the next-generation capability needed for the complex nanometer designs which
chipmakers face today. For leading-edge custom digital designers, verification
can no longer be limited to either dynamic or static analysis at the
circuit-level. We believe our innovative hybrid technology in HANEX(TM)
delivers a new level of accuracy and performance by optimizing the advantages
of both dynamic and static analysis methods."
About HANEX
HANEX uses a hybrid of dynamic and static methods to automatically identify
critical paths, including the impact of crosstalk effects on signal timing for
custom CMOS digital designs with millions of elements. HANEX fills the gap
between pure static analysis methods and the need for more accurate timing
simulation to ensure success in the latest nanometer silicon processes at 130nm
and below.
"For high-performance digital designs, many engineers who use static analysis
experience insufficient timing accuracy because of undetected dynamic nanometer
effects such as crosstalk," Bell stated. "As a result, digital IC manufacturers
can produce silicon that fails to meet performance objectives even though
static timing sign-off analysis has been completed. We believe HANEX delivers
results with the accuracy of dynamic simulation and the speed and comprehensive
coverage of static analysis."
